Recent studies of purchasing power parity (PPP) use panel tests that fail to take into account heterogeneity in the speed of mean reversion across real exchange rates. In contrast to several other severe restrictions of panel models and tests of PPP, the assumption of homogeneous mean reversion...

It is well known that returns on foreign exchange rates are not normal and tend to have fat-tailed distributions. Although the precise magnitude of the tail-fatness is crucial for applications such as risk analysis, little consensus exists in this respect due to estimation problems. In this...

Copulas offer financial risk managers a powerful tool to model the dependence between the different elements of a portfolio and are preferable to the traditional, correlation-based approach. In this paper we show the importance of selecting an accurate copula for risk management. We extend...

In this paper, we present the results of an international survey among 313 CFOs on capital budgeting, cost of capital, capital structure, and corporate governance. We extend previous results of Graham and Harvey (2001) by broadening their sample internationally, by including corporate...

This paper analyzes the cost of capital of firms with foreign equity listings. Our purpose is to shed light on the question whether international and domestic asset pricing models yield a different estimate of the cost of capital for cross-listed stocks. We distinguish between (i) the...

Using an international database containing 103 German, UK and US ethical mutual funds we review and extend previous research on ethical mutual fund performance. By applying a multi-factor Carhart (1997) model we solve the benchmark problem most prior ethical studies suffered from. After...

In this paper we develop an asset allocation model which allocates assets by maximising expected return subject to the constraint that the expected maximum loss should meet the Value-at-Risk limits set by the risk manager. Similar to the mean-variance approach a performance index like the Sharpe...

We examine the extent to which the consequences of insider trading for a financial market depend on the trading mechanism in an experimental multiple dealer asset market. In this market, five professional securities traders make a market in a single asset. In each trading round, one of the...

This paper examines trading costs in markets where dealers search for price quotes (such as multiple-dealer equity markets and foreign exchange). Using an experimental market, we compare four popular models for estimating effective spreads. The theoretical implications of 'bid-ask bounce' are...

It is a well-known stylized fact that financial returns are non-normal and tend to have fat-tailed distributions. This paper presents a methodology that accurately estimates the degree of fat-tailedness, characterized by the tail-index, in small samples. We present a simple approach based on the...
